Answer:

22.3 km²

Step-by-step explanation:

The formula for the area of a circle is

A = πr²

r = ½d, so

A = π(½d)² = ¼πd²

A = ¼ × π × (16/3)² = ¼ × π × 256/9 ≈ 22.3 km²

The equation of a line is x + 4y = 15.

alukav5142 [94]

<h2>Answer: c.) ¹⁵/₄</h2>

Step-by-step explanation:

If we transpose the equation into the slope-intercept form (y = mx + c), the value of c is the y-intercept.

since x + 4y = 15

then 4y = - x + 15

∴ y = -¹/₄ x + ¹⁵/₄

<h3>⇒ the y-intercept for the line x + 4y = 15 is ¹⁵/₄</h3>

traveling at 45 mph, how many minutes, rounded to the nearest whole number, does it take to drive 240 miles from Orlando to Miam

liq [111]

$v=\frac{d}{t}\\\\v-velocity;\ d-distance;\ t-time\\-------------------------\\v=\frac{d}{t}\ \ \ \ |multiply\ both\ sides\ by\ t\\vt=d\ \ \ \ |divide\ both\ sides\ by\ v\\\\t=\frac{d}{v}\\------------------------$

$v=45\ mph;\ d=240\ mi\\\\t=\frac{240}{45}=\frac{240:15}{45:15}=\frac{16}{3}\ (h)\\\\1h=60min\\\\therefore\\\\t=\frac{16}{3}\cdot60min=16\cdot20min=\boxed{320min}$
